I love applying Navratan Hair Oil in summers when the heat is at its max. It cools down my head and makes me very relaxed and calm. It my most favourite hair oil which I love to apply. On applying it, it takes 2 mins to start its coolness. One of the other reasons for applying it is also the fragrance, I just love the fragrance which it leveas on our hair, its fragrance make the mood even calmer and relaxing.
